Bohuzel jedeme jenom na Intelu, takze budeme muset aplikovat patch do jadra, ktery nam pravdepodobne o neco uzere z CPU vykonu. Jak to pisu, tak patch pro nase jadro jeste neni; pokud neprijde od OpenVZ, naportujeme patch od Red Hatu, jakmile bude venku. V takovem pripade upravime plan rebootu, abychom meli vic casu to otestovat.

Unfortunately Intel is all we have now, so we have to apply a workaround as a kernel patch. Which, for one, will slow down performance of our systems. And as of writing this, the patch is not out for our kernel yet (or any nicely portable version for this venerable kernel); but should be soon, at least from Red Hat, if not OpenVZ team (in which case we'll change the announcements accordingly to allow for more QA before deploying). There's a lot of sources, for one of them all (and then Your Favorite Search Engine should spit out tons of other resources if you search for 'Intel PTI bug') -> https://www.reddit.com/r/sysadmin/comments/7nl8r0/intel_bug_incoming/ -----BEGIN BASE64 ENCODED PARSEABLE JSON----- eyJpZCI6NDIzLCJwbGFubmVkIjp0cnVlLCJiZWdpbnNfYXQiOiIyMDE4LTAx LTA1VDAxOjAwOjAwKzAxOjAwIiwiZHVyYXRpb24iOjYwLCJ0eXBlIjoicmVz dGFydCIsImVudGl0aWVzIjpbeyJuYW1lIjoiTm9kZSIsImlkIjo1LCJsYWJl bCI6InZwc2FkbWluLnByZyJ9LHsibmFtZSI6Ik5vZGUiLCJpZCI6MTExLCJs YWJlbCI6Im5vZGUxMC5wcmcifSx7Im5hbWUiOiJOb2RlIiwiaWQiOjExMiwi bGFiZWwiOiJub2RlMTEucHJnIn0seyJuYW1lIjoiTm9kZSIsImlkIjoxMTMs ImxhYmVsIjoibm9kZTEyLnByZyJ9LHsibmFtZSI6Ik5vZGUiLCJpZCI6MTE0 LCJsYWJlbCI6Im5vZGUxMy5wcmcifSx7Im5hbWUiOiJOb2RlIiwiaWQiOjEx NSwibGFiZWwiOiJub2RlMTQucHJnIn0seyJuYW1lIjoiTm9kZSIsImlkIjoy MTAsImxhYmVsIjoibm9kZTEuYnJxIn1dLCJoYW5kbGVycyI6WyJQYXZlbCDF oG5hamRyIiwiSmFrdWIgU2tva2FuIiwiUmljaGFyZCBNYXJrbyJdLCJ0cmFu c2xhdGlvbnMiOnsiZW4iOnsic3VtbWFyeSI6IkludGVsIENQVSBidWcgd29y a2Fyb3VuZCIsImRlc2NyaXB0aW9uIjoiQSBzZXZlcmUgYnVnIGhhcyBiZWVu IGZvdW5kIGluIEludGVsIENQVXMuIFVuZm9ydHVuYXRlbHkgSW50ZWwgaXMg YWxsXHJcbndlIGhhdmUgbm93LCBzbyB3ZSBoYXZlIHRvIGFwcGx5IGEgd29y a2Fyb3VuZCBhcyBhIGtlcm5lbCBwYXRjaC4gV2hpY2gsXHJcbmZvciBvbmUs IHdpbGwgc2xvdyBkb3duIHBlcmZvcm1hbmNlIG9mIG91ciBzeXN0ZW1zLiBB bmQgYXMgb2Ygd3JpdGluZ1xyXG50aGlzLCB0aGUgcGF0Y2ggaXMgbm90IG91 dCBmb3Igb3VyIGtlcm5lbCB5ZXQgKG9yIGFueSBuaWNlbHkgcG9ydGFibGVc clxudmVyc2lvbiBmb3IgdGhpcyB2ZW5lcmFibGUga2VybmVsKTsgYnV0IHNo b3VsZCBiZSBzb29uLCBhdCBsZWFzdCBmcm9tXHJcblJlZCBIYXQsIGlmIG5v dCBPcGVuVlogdGVhbSAoaW4gd2hpY2ggY2FzZSB3ZSdsbCBjaGFuZ2UgdGhl IGFubm91bmNlbWVudHNcclxuYWNjb3JkaW5nbHkgdG8gYWxsb3cgZm9yIG1v cmUgUUEgYmVmb3JlIGRlcGxveWluZykuXHJcblxyXG5UaGVyZSdzIGEgbG90 IG9mIHNvdXJjZXMsIGZvciBvbmUgb2YgdGhlbSBhbGwgKGFuZCB0aGVuIFlv dXIgRmF2b3JpdGVcclxuU2VhcmNoIEVuZ2luZSBzaG91bGQgc3BpdCBvdXQg dG9ucyBvZiBvdGhlciByZXNvdXJjZXMgaWYgeW91IHNlYXJjaFxyXG5mb3Ig J0ludGVsIFBUSSBidWcnKSAtXHUwMDNlXHJcblxyXG5odHRwczovL3d3dy5y ZWRkaXQuY29tL3Ivc3lzYWRtaW4vY29tbWVudHMvN25sOHIwL2ludGVsX2J1 Z19pbmNvbWluZy8ifSwiY3MiOnsic3VtbWFyeSI6IkFwbGlrb3ZhbmkgemFw bGF0eSBwcm8gY2h5YnUgdiBJbnRlbCBDUFUiLCJkZXNjcmlwdGlvbiI6IkJ5 bGEgbmFsZXplbmEgdmF6bmEgY2h5YmEgdiBJbnRlbGljaCBwcm9jZXNvcmVj aC4gQm9odXplbCBqZWRlbWUgamVub21cclxubmEgSW50ZWx1LCB0YWt6ZSBi dWRlbWUgbXVzZXQgYXBsaWtvdmF0IHBhdGNoIGRvIGphZHJhLCBrdGVyeSBu YW1cclxucHJhdmRlcG9kb2JuZSBvIG5lY28gdXplcmUgeiBDUFUgdnlrb251 LiBKYWsgdG8gcGlzdSwgdGFrIHBhdGNoIHBybyBuYXNlXHJcbmphZHJvIGpl c3RlIG5lbmk7IHBva3VkIG5lcHJpamRlIG9kIE9wZW5WWiwgbmFwb3J0dWpl bWUgcGF0Y2ggb2QgUmVkIEhhdHUsXHJcbmpha21pbGUgYnVkZSB2ZW5rdS4g ViB0YWtvdmVtIHByaXBhZGUgdXByYXZpbWUgcGxhbiByZWJvb3R1LCBhYnlj aG9tIG1lbGlcclxudmljIGNhc3UgdG8gb3Rlc3RvdmF0LlxyXG5cclxuT2Rr YXp1LCBvIGNvIGpkZSwgamUgaG9kbmUsIGtkeXp0YWsgaG9kdGUgJ0ludGVs IFBUSSBidWcnIGRvIFN2ZWhvXHJcbk9ibGliZW5laG8gVnlobGVkYXZhY2Ug KHRtKSwgdnlwbGl2bmUgdG9obyBocm9tYWR1IC1cdTAwM2VcclxuXHJcbmh0 dHBzOi8vd3d3LnJlZGRpdC5jb20vci9zeXNhZG1pbi9jb21tZW50cy83bmw4 cjAvaW50ZWxfYnVnX2luY29taW5nLyJ9fX0= -----END BASE64 ENCODED PARSEABLE JSON-----
